Airtac MAC Stainless Steel Mini Air Cylinder MAC25X130SCM
The AirTAC Airtac MAC Stainless Steel Mini Air Cylinder MAC25X130SCM is a genuine double acting + cushion standard round-body mini air cylinder with a Ø25mm bore and 130mm stroke, 1/8" air ports and a stainless-steel barrel with a hard-chrome-plated rod for reliable, mildly corrosion-resistant service. A variable air cushion at both ends lets you tune end-of-stroke deceleration on site.

About the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X130SCM
With a CM round-end back cover, this MAC25X130SCM seats flush against a machine wall without an intermediate bracket, and the rolled stainless barrel behind it resists washdown corrosion. Double acting throughout, the 25 mm bore extends with 245.3 N at 0.5 MPa and retracts at 206.1 N. The hard-chrome plated rod is 10 mm across, matched to an M10x1.25 male thread.
Budget about 147 N for real work at 0.5 MPa - roughly what it takes to index a light slider or close a small gate against spring pressure. Twin needle valves give a variable air cushion at each end, so speeds up to 800 mm/s do not translate into cracked covers. If the job later needs position holding, the double-rod MACD or a pilot check valve covers what this cylinder cannot: with no air applied the piston simply drifts. The built-in magnet feeds CMSG or EMSG switches for end-of-stroke signals.

Specifications follow the official AirTAC MA-series datasheet. Barrel: stainless-steel tube (round-body, riveted rolling-packed construction); piston rod: carbon steel with 20µm hard-chrome plating; covers: aluminium alloy. Thread options: PT (blank) / G / NPT. Every MA-series cylinder ships with a built-in magnet for CMSG / DMSG / EMSG position sensors.
Theoretical Output Force (Ø25mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 245 N | 206 N |
| 0.7 MPa | 344 N | 289 N |
| Max (@1.0 MPa) | 50 kgf | |
Actual usable force is lower than theoretical due to friction and back-pressure. Size with a safety margin.

Where the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X130SCM Is Used
CNC jig clamp
Mounted flush through the CM round-end boss, it clamps cast brackets for a boring op with about 147 N of working force at 0.5 MPa.
PET bottle gate
A 130 mm deflector flap sorts bottles between two filling lanes; twin cushions stop the flap banging at the top of the 30-800 mm/s band.
Connector seating press
Seats automotive connectors in a bench fixture - 245.3 N at 0.5 MPa, and roughly 12 kg can be raised vertically with a 2:1 margin.
Is the Airtac MAC Stainless Steel Mini Air Cylinder MAC25X130SCM the Right Cylinder?
Sizing check: a 20 mm bore yields 157.0 N at 0.5 MPa while a 32 mm bore yields 402.2 N, so this 25 mm barrel sits mid-family at 245.3 N. Over 130 mm of travel keep side loads off the rod or add external guidance, or the chrome surface will wear unevenly. LB foot, FA flange and SDB pivot brackets bolt to the same body, with the CM round-end cover chosen here for flush panel mounting. Supply spans 0.15-1.0 MPa (22-145 psi), and on air loss the piston coasts rather than holding - plan a lock if the position must stick.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) is standard for sensors
- ✓ Back cover (CA/U/CM) & mount (FA/LB/SDB)
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Do not dismantle the riveted front/back covers.
- check On first run, back off the cushion screws and release gradually.
- check Installation by qualified personnel per AirTAC docs.
Airtac MAC Stainless Steel Mini Air Cylinder MAC25X130SCM FAQ
Extend force is 245.3 N and retract 206.1 N at 0.5 MPa supply; at 0.7 MPa the pair becomes 343.4 N and 288.5 N, peaking near 50 kgf theoretically at 1.0 MPa. Bore is 25 mm, rod 10 mm with M10x1.25 thread, ports 1/8", and the 130 mm stroke is a standard option up to 500 mm on this bore.
Its rounded boss seats flush into a machined recess or flat panel, so the cylinder mounts without adapter plates. FA flange, LB foot and SDB pivot brackets also fit the barrel, and I or Y rod knuckles thread onto the M10x1.25 rod end.
